Michele Mendi

A polytypic Holarctic passerine, breeding from Iberia in W Europe to Alaska and Canada. Migratory, wintering ranges extended from SW Europe and Africa to SE Asia (Collar 2005). Six subspecies breed in Europe: L. s. azuricollis (Iberia only, Johnsen et al., 2006), namnetum (mostly Atlantic wetlands of France), cyanecula (from E France to Russia), svecica (N Scandinavia to N Russia), volgae (from E Ukraine to Russia), magna (Caucasus).

Connectivité globale pour Gorgebleue à miroir

Two main migratory axes; SW (namnetum, cyanecula, azuricollIs) (Arizaga & Tamayo 2013) or SE (svecica, magna, volgae) (Collar 2005). Subspecies azuricollis recently revealed to winter in W Africa (Lomas-Vega et al. 2019)., while namnetum migrates along the coast of N Iberia (Arizaga et al. 2006) to overwinter mainly in Portugal/N Africa (Zucca & Jiguet 2002) and cyanecula overwinters from S Europe to W Africa. Migration is on a broad front, although there is some connectivity: Bluethroats breeding further east were also located further east during autumn migration, winter and spring. There are few data for svecica  outside Scandinavia, but recoveries spread across a NW-SE axis, across to India. Studies with geolocators confirm an Indo-European flyway (Lislevand et al. 2015). Few data for the E and Caucasian populations. There are few data for the E and Caucasian populations. Birds breeding in SE Russia/Caucasus have been recovered in Israel and the E Mediterranean.

Contrôles par Condition for Gorgebleue à miroir

Most recoveries are of birds recaptured for ringing. Before 1960 ca. 15% of recoveries were of birds found dead, including those shot or sick/wounded.

Annual Movements for Gorgebleue à miroir

Birds leave the breeding quarters soon after breeding, mostly in Jul/Aug, up to Sep in very N populations (Lislevand et al. 2015). Passage in W Europe starts in mid-Aug, peaking in Sep (Arizaga et al. 2010). By Nov, most birds already found at their wintering sites. Spring migration starts in Mar, peaking in Apr in S/C Europe and also the Indo-European flyway-associated Bluethroats (Lislevand et al. 2015),  arrival on the northern European breeding grounds (Scandinavian birds) is in May; later than for the W/C European populations. Migratory speed seems to be slow, assessed to be <200 km/day (including stopovers; Lislevand et al. 2015), though probably much faster in spring (Lomas-Vega et al. 2019).

Connectivité par mois par région pour Gorgebleue à miroir

There are fewer recoveries during spring migration than in autumn. Autumn recoveries There are fewer recoveries during spring migration than in autumn. Autumn recoveries cyanecula are common both on the Atlantic and the Mediterranean coasts of W/C Europe, while in spring most recoveries show a Mediterranean–biased distribution, suggesting loop migration at least in this subspecies are common both on the Atlantic and the Mediterranean coasts of W/C Europe, while in spring most recoveries show a Mediterranean–biased distribution, suggesting loop migration at least in this subspecies (Arizaga & Tamayo 2013). In autumn, svecica moves through C Asia from Sep to Oct/Nov; reaching India from late Sep to Oct/Nov (Lislevand et al. 2015).
